SPECIFICATION forming part of Letters Patent No. 349,949. dated September 28, 1886.

Application filed May 24,1886. Serial No. 103,182. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM MILD, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvementin Links, which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 is a perspective view of my improved link for pump-chains with. the cup attached thereto. Fig. 2 is a perspective view of the link with the cup detached; Fig. 3, a view of the straight section of wire used in the construction of the link; Figs. 4, 5, ti, and 7, views of the link at different stages of construction. Fig. 8 shows a straight section of wire used in forming the loop for the reception of the cup; Figs. 9 and 10, views of the loop attached to the link, showing different stages of construction.

My invention relates to an improvement in links for pump-chains; and it consists in a link V-shaped and diverging at the ends, so as to connect with the opposite link and with loops at the opposite ends, and small in the center to accommodate the ends of a circular band, so disposed as to receive a cup therein, the V-shaped end of the link having a central indentation to prevent the opposite link from being moved laterally, and thus twisting or entangling the chain, each alternate link being provided with a band for attaching the cup, while the other link is left plain, the cup and link all being galvanized, so as to be secured together rigidly, all of which will now be fully set forth in detail.

In the accompanying drawings, A repre sents a link,having at its upper end an indentation, B, with lateral loops 0, to which the end of the opposite link is attached. Centrally the sides of the link are curved inwardl y so as to to join each other and form a waist or narrow part, as shown at D. The opposite or lower end of the link is formed with upturned loops E, so disposed with the loops C that the opposite link may engage therewith, and for this purpose the loop ends E of thelink diverge to near the width of the upper end of the link. Fig. 2 shows this link with the corresponding links shown by broken lines. I next provide a circular wire piece, G, as shown in Fig. 9, with the ends crossed, as shown at H, and then with the ends extending out- \vardly, as shown at I, Fig. 10. The angles between the two ends J of this band are designed to receive the central portion or waist, D, of the link A, as shown in Fig. 6, with the outer ends, I, of this section clinched down around the said link A, as shown at K, Fig. 10, with the hoop G at right angles with the body of the link A. This hoop G is designed to be of such a size that it will receive the cup L about midway vertically, the entire device then being galvanized, which rigidly secures the hoop G to the body of thelink A, and also the cup to the hoop G. All the successive links in the chain are formed with the body of the link A as shown completed in Figs. 6 and 7; but only each alternatelinkis provided with the hoop G and the cup L. I find it especially necessary to form the link with the indentation or recess B at the upper end, to obviate the tendency of the end of the opposite link from slipping or twisting sidewise in case the chain becomes slack, which would be very natural if this part of the link were formed straight across, or without an indentation of this kind. As will be noticed, the cup L does not come in contact either at its upper or lower parts with the body of the link A, as the cup is held entirely in position by means of the hoop G being galvanized in position. The galvanizing material alsosecures thehoop G at right angles rigidly in position with the link A.

Having described my invention,whatl claim as new is 1. A link formed of a single piece indented at one end, the central part curved inwardly, and the opposite end provided at each of its two extremities with a loop, substantially as described.

2. The combination of a link made of a single piece, indented at one end, curved inwardly at the central part, and provided with a loop at each of its opposite ends, with a hoop having its endssecured in position around the waist of the link, substantially as described.

3. The combination of the link A, having the indentations B and loop 0 at one end, the central part, 1), formed narrow, and the opposite end with loops E, with the cup'hoop G, so disposedvas to clasp the narrowest part of the link, substantially as herein set forth.

4. The combination of the link A, having therein the indentations B, loops 0 and E, with the hoop G, secured in position at the central portion, D, of the link to receive the cup L, substantially as herein set forth.

5. The combination of the cup L, disposed centrally within the hoop G, attached to the central portion, D, of the link A, the said link having the connecting loops C and E and the indentations B,'the whole arranged as and for the purpose substantially as herein set forth and described. 1 5

In testimony that I claim the foregoing I have hereunto set my hand, this 10th day of April, 1886, in presence of witnesses.
